No scan results - Pixel 6a Android 13

[johnnyzen]

Hi, during testing devices, I am not getting any results for a Pixel 6a on Android 13.

Working fine on:
Samsung - Galaxy Fold Android 13,
Samsung - (industry phone) Android 12
Pixel 4 - Android 12 and Android 13.

I am aware of many issues at the moment with pixel / android 13 and bluetooth.

Just wondered if anyone else having same issue.

Thanks.

I'm having the same issue on a Pixel 7 v 13: onScannerRegistered() - status=0 scannerId=3 mScannerId=0 shows up in the log and everything appears to be working, but no success or error callbacks are ever fired.

In android 13, after adding below line is working fine for me.

<uses-permission android:name="android.permission.BLUETOOTH_SCAN"
        android:usesPermissionFlags="neverForLocation"
        tools:targetApi="s"/>

any update ?

found follow code about No scan results in Samsung S22 Ultra Android 13

class ScanResponse {
    var localName: String? = null
}

fun parseName(scanResult: ScanResult): String? {
    if (Build.VERSION.SDK_INT >= 33) {
        // Android 13
        scanResult.scanRecord?.let { scanRecord ->
            if (scanRecord.deviceName != null) {
                return scanRecord.deviceName
            } else {
                // If deviceName is null, parse the scan response packet for better compatibility
                scanRecord.bytes?.let { rawBytes ->
                    // rawBytes total length is 62 bytes, the first half is 31 bytes of advertising data,
                    // and the second half is 31 bytes of scan response data
                    val scanResponse = parseScanResponse(rawBytes, 31)
                    return scanResponse.localName
                }
            }
        }
    }

    return scanResult.scanRecord?.deviceName
}

@TargetApi(33)

    val scanResponse = ScanResponse()
    var pos = start
    var len = bytes[pos].toInt().and(0xff)
    var dataType: Int
    var data: ByteArray
    while (len > 0) {
        dataType = bytes[++pos].toInt().and(0xff)
        data = bytes.copyOfRange(pos, pos + len - 1)
        when (dataType) {

            ScanRecord.DATA_TYPE_LOCAL_NAME_COMPLETE -> {
                val localName = String(data)
                println("localName: $localName")
                scanResponse.localName = localName
            }
            // If you need to parse other data, add other DATA_TYPE_xxx as needed
            else -> {
